OroWheat Bread Stores sell them. I only think they can be found in Washington, & California...My dad lives in Washington, and that is where he gets his from...I loved them, and thought I could get them back home somewhere in Arkansas...Not the case...Guess I will have to start having him send me a case or two.
They used to sell Tuc crackers around the midwest but I have not seen them in years. I understand that Safeway stores still carry them though. You may try to see if there is a store close or even email safeway to see if they do have them and if there is a store close to you.
If you have a Cub Foods nearby, you may want to check there. Although I'm in MN, that's where I found mine. I've been waiting for almost 30 years to find them here in the US! I used to live in Denmark, which is where I developed my love of them. Now if I could just find request!
